WEEDER ATTACHMENT FOR C'ULTIVATORS.

SPECIFICATION forming part of'Letters Patent N o. 701,844, dated June10, 1902. Application filed December 14, i901. Serial No. 851913. (Nomodel.)

To @ZL whom it may concern,.-

Be it known that I, EDWINP. CLAPP, a citizon of the United States, and aresident of North Rush, in the county of Monroe and State of .New York,have invented certain new and useful Improvements in Weeder At-.tachments for Cultivators and Like Agricultural Implements, of whichthe following is a specification.

This invention relates to weeder attachments for cultivators, and hasfor its object to provide a weeder in connection with a cul showing theweeder attachment as itis being reversed. Fig. 3 is a side view from theleft of certain parts of the cultivator. Fig. 4 is a Isection on theline t 4t of Fig. 2, enlarged.

Fig. 5 is a side elevation of another form of the weeder attachmentapplied to a culti- Fig. b' is a rear View of the same weeder attachmentand cultivator shown in Fig. 5, and Fig. 7 is a View from above of partsof the weeder attachment and cultivator shown in the two iigures lastreferred to. Fig. Sis a section on the line 88 The frame of theculti-vator, which may be of any suitable construction, is representedas composed of the frame A, consisting of several rails suitablyfastened together, a suitable central beam A', rigidly connectedtherewith, and the handle-bars A2 A2, secu red to the frame at anyconvenient point. The beam A' carries the cultivator-teeth B B', and theside rails each carry one of the pairs of teeth B2 B2 and B3 B3. A bar Cis supported above the central beam A', as by thestandards D D', (seeFig. 3,) and the weeder is carried by au arm E, which is pivoted uponthe bar C, as shown in Figs. l and 2. The weeder consists of the frame Fand the teeth G, secured thereto in any suitable manner. In

Fig. 4 is shown the preferred way for attaching these teeth G to theframe F. By referring to said iigures it will be seen that the teeth arebent at right angles and that their upper ends q are passed throughholes f in the frame F and are finished iu loops g'. Each tooth issecured to the part F' of the frame by a bolt g2, which is passedthrough said loop and frame and secured by a nut. The frame F is in turnsecured to an arm H, which projects rearwardly from the sprocketwheel I,and the latter is pivotally secured to the arm E by the bolt J, whichpasses through a bracket K upon the end of the arm E. (See Fig. 4.)Another sprocket-Wheel M is rigidly l secured to the cultivator, as atthe bracket D', in the same plane with the sprocket-Wheel I, and anendless chain-L connects the two wheels. l,

The means Vwhereby the arm E and the weeder are respectively rotated isas follows: A rod N, one end of which is bent into a crank @tand handle'n' and the other end of which, n3, is bent at an angle with the mainportion of the arm, is journaled at 'n2 and n4 upon one of the braces A3for the handle-bar A2 and on-the bracket D', respectively. The end n3 ofthe said rod N is slotted, as shown by a5 in Fig. 2, so as to contain apin e,'that projects from the arm E. Whenthe crank end n of the rod N isturned, the arm E is raised by it into the position shown by dottedlines in Fig. 2, and fromthat position it may be dropped to the other-side of the cultivator. As the arm E is [raised in the manner describedthe sprocket-wheel- I is caused to rotate, because of its connectionVthrough the chain L with the rigid sprocket-wheel M, and the weeder,because of its rigid connection with the said sprocket-wheel I, iscaused to rotate with reference tothe said arm E. The relative size ofthe sprocket-wheels I and M is such that when the arm E is transferredfrom its normal position on one side of the cultivator to its normalposition on the other side the weeder will have its upright position, inwhich the teeth are vertical in both positions. The positions of theframe F and the teeth G of the Weeder when the .arm E is raised at rightangles to its normal position are shown by dotted lines in Fig. 2. Theweight of the weeder would cause it to retain its said normal verticalposition at all times even if the said sprocket-wheel I was notconnected by the chain Lwith the rigid sprocket- IOO wheel M, asdescribed above; but the said connection affords a positive means bywhich the vertical position of the weeder is assured. A slidingconnection, such as the slot yn.5 in the end a3 of the rod N and the pine, is essential between the arm E and the rod N when the latter isplaced at an angle to the former, as shown in the drawings, for thereason that the point of engagement between said parts changes when thearm E is rotated. The arm E may be braced in any suitable manuel', as bythe brace E'.

The operation ofthe weederdescribedabove is now obvious. When thecultivator is used between rows of plants, the weeder (assuming that itis in the position with reference to the cultivator in which it isrepresented in the drawings) will uncover the row of plants on the leftof the cultivator and destroy any small weeds that may be there. At thesame time the weeder levels the rows. \Vhen the cultivator is to be runback in the opposite direction in the space between the row of plantsthat was on its right during said first operation and the next row, thearm E is turned over to the other side of the cultivator by the rod N,and with it the weeder, which will assume a position on the right of thecultivator corresponding to that which it before occupied on the left.The weeder will now weed and level the next row of plants, which is thaton the right of the cultivator. In this way by reversing the positionofthe weeder at the end of each row the several rows of plants in afield will be weeded and leveled successively. The operator is thusenabled to weed and level successively all of the rows of plants withoutrunning his cultivator over the same ground twice and without stoppingit to adjust the weeder.

In Figs. 5 to '7, inclusive, the weeder is represented as attached to asulky-cultivator- The cultivator-teeth are carried by the bars O O,which are respectively pivoted to the frame I), as at p p. The teeth areraised by means of levers Q, Q, which are respectively pivoted to thesulky-frame, as at q q, and the connecting-rod g q or by other suitablemeans. The teeth G of the weeder are represented as attached to theframes F2 F2 in the lnanner described with reference to the form ofweeder first described, and the frames F2 F2 are rigidly secured tocastings O2 O2, respectively, which are in turn pivotally secured tobrackets O O, respectively, as by the bolts o 0. The brackets arerigidly secured to the bars O O, respectively. T T are correspondingparts of the cultivator-frame that carry cultivator-teeth and aresecured to the other bar O O, as by the bolt t t. The bars O O and T Tare extended back, as shown in Fig. 7, and afford a seat for the weederswhen they are not in use and tilted back into the position shown in Fig.G. T T represent other bars of the cultivator that carry one or more ofits teeth. Handles U U afford one means of elevating the weederframes.Other means may be employed-as, for example, ropes V V, which aresecured to the frame F2 F2 of the weeders, or both handles and ropes maybe employed to advantage, for in some positions of the weeders the ropescan be used to raise or lower the weeders when the handles are notconvenient therefor. The upper ends of the ropes V V are represented asattached to the drivers seat XV, as at o fr.
